Database Internals.

When it comes to choosing, using, and maintaining a database, understanding its internals is essential. But with so many distributed databases and tools available today, it’s often difficult to understand what each one offers and how they differ. With this practical guide, Alex Petrov guides developers through the concepts behind modern database and storage engine internals.

Throughout the book, you’ll explore relevant material gleaned from numerous books, papers, blog posts, and the source code of several open source databases. These resources are listed at the end of parts one and two. You’ll discover that the most significant distinctions among many modern databases reside in subsystems that determine how storage is organized and how data is distributed

Android - Clean Architecture - Kotlin

The purpose of this repo is to follow up Clean Architecture principles by bringing them to Android. It is worth saying that the idea is to take advantage of the Kotlin Programming Language features plus also pull in lessons learned and ideas from other interesting approaches like Functional Programming.

kotlinx.coroutines is a library support for Kotlin coroutines with multiplatform support.

Usage:

suspend fun main() = coroutineScope {
launch {
delay(1000)
println("Kotlin Coroutines World!")
}
println("Hello")
}

MNN is a highly efficient and lightweight deep learning framework. It supports inference and training of deep learning models, and has industry leading performance for inference and training on-device. At present, MNN has been integrated in more than 30 apps of Alibaba Inc, such as Taobao, Tmall, Youku, Dingtalk, Xianyu and etc., covering more than 70 usage scenarios such as live broadcast, short video capture, search recommendation, product searching by image, interactive marketing, equity distribution, security risk control. In addition, MNN is also used on embedded devices, such as IoT.

Open Neural Network Exchange (ONNX) is an open ecosystem that empowers AI developers to choose the right tools as their project evolves. ONNX provides an open source format for AI models, both deep learning and traditional ML. It defines an extensible computation graph model, as well as definitions of built-in operators and standard data types.

Apache Doris is an easy-to-use, high-performance and real-time analytical database based on MPP architecture, known for its extreme speed and ease of use. It only requires a sub-second response time to return query results under massive data and can support not only high-concurrent point query scenarios but also high-throughput complex analysis scenarios.

Based on this, Apache Doris can better meet the scenarios of report analysis, ad-hoc query, unified data warehouse, Data Lake Query Acceleration, etc. Users can build user behavior analysis, AB test platform, log retrieval analysis, user portrait analysis, order analysis, and other applications on top of this.

Modern C++ Tutorial.

Modern C++ introduces many features into traditional C++ which bring the entire language to a new level of modernization. Modern C++ not only enhances the usability of the C++ language itself, but the modification of the auto keyword semantics gives us more confidence in manipulating extremely complex template types. At the same time, a lot of enhancements have been made to the language runtime. The emergence of Lambda expressions has given C++ the "closure" feature of "anonymous functions", which are in almost all modern programming languages ​​(such as Python, Swift, etc). It has become commonplace, and the emergence of rvalue references has solved the problem of temporary object efficiency that C++ has long been criticized for.

Bun is a modern JavaScript runtime like Node or Deno. It was built from scratch to focus on three main things:

- Start fast.
- New levels of performance.
- Being a great and complete tool.

Bun is designed as a drop-in replacement for your current JavaScript & TypeScript apps or scripts — on your local computer, server or on the edge. Bun natively implements hundreds of Node.js and Web APIs, including ~90% of Node-API functions (native modules), fs, path, Buffer and more.

The goal of Bun is to run most of the world's JavaScript outside of browsers, bringing performance and complexity enhancements to your future infrastructure, as well as developer productivity through better, simpler tooling.
